Quick Start
Install any plugin in any agent (Claude Code, Cursor, Codex, …) with vercel-labs/skills:
npx skills add 2389-research/simmer
Or natively in Claude Code:
# Add the marketplace, then install any plugin
/plugin marketplace add 2389-research/claude-plugins
/plugin install simmer@2389-research
The 4 MCP servers (journal, socialmedia, slack-mcp, agent-drugs) install via Claude Code only — they ship no skills for npx.
